[Clinical characteristics of migraine without aura].

A detailed study of the clinical characteristics of migraine without aura (MOA) reveals some interesting data. A questionnaire was returned by 200 patients who met the International Headache Society criteria for MOA. The peak of onset of migraine was between 10 and 19 years of age. The headache was side-locked in 19%. It was exclusively bilateral in 9%. The majority (86.2%) of the patients who described headaches in only one site located them in the fronto-temporal area. Neck pain was associated with migraine attacks in 70.5% and face pain in 73.5%. A pounding quality was noted by 81%. Every patient described the headache as moderate to severe. Only 55% stated that it was aggravated by routine physical activity. Nausea occurred in 91%, photo and phonophobia in 77%, and vomiting in 50%. This close look at MOA uncovers a great complexity of symptoms.
